The mc505 has nothing to see with the mc303.This is something else. Its sounds 98,its sound professional and it sound good.The great sounding has to do with two things:with the mc303 you have 1 sound for 1 channel,with the 505 you can have 4 different sounds for 1 channel. Second;A great choise of effect types make from every sound a great sound.You make pumping beats,flipping trancy sounds and hard basses... ..when you have found how everything works,and thats a little bit the toughest thing on the 505.GREAT MACHINE.

Comments About the Sounds:
These sounds are a lot better than the mc303 sounds.The 505 sounds are the sounds you here today in your favorite dance track.This isn't old crap,they sound good and professional.
